Step‑by‑Step Instructions for Baked French Onion Gnocchi
Step 1: Sauté the Onions
In a heavy pot or Dutch oven, melt 2 tablespoons of butter and 1 tablespoon of olive oil over medium heat. Once shimmering, add 3 large thinly sliced onions, seasoning with salt and pepper. Cook for about 45 minutes, stirring occasionally until the onions turn golden brown and jammy. If they start to stick, add a splash of broth to keep them from burning.
Step 2: Add Sweetness
After achieving a rich color, sprinkle in 1 tablespoon of brown sugar, stirring it into the onions. Continue cooking for an additional 2 minutes to enhance their natural sweetness. You’ll notice a deeper flavor developing, perfect for our Baked French Onion Gnocchi.
Step 3: Deglaze the Pan
Pour in ½ cup of white wine (if using) and scrape any browned bits from the bottom of the pot to incorporate all those delicious flavors. Let it simmer for a few minutes until the wine reduces slightly, adding even more depth to the dish.
Step 4: Build the Broth
Next, add 4 cups of vegetable or beef broth, 1 teaspoon of dried thyme, and 2 bay leaves to the pot. Stir well and bring the mixture to a gentle simmer. Allow it to cook for 15 minutes, letting all the flavors meld beautifully together.
Step 5: Preheat the Oven
While the broth simmers, preheat your oven to 425°F (220°C). This ensures it reaches the right temperature for baking the cheese-topped Gnocchi and creates that bubbly, golden finish we crave in this comforting dish.
Step 6: Cook the Gnocchi
Stir in 1 pound of gnocchi into the simmering broth. Allow them to cook undisturbed for about 3-4 minutes until they begin to float to the surface. This indicates they are cooked through. Remove the thyme stems and bay leaves for a smooth, lovely finish to the broth.
Step 7: Cheese It Up
Mix in 1 cup of grated Gruyère cheese and ¼ cup of grated Parmesan cheese, stirring until melted and well combined. Pour the Gnocchi and broth mixture into a baking dish, ensuring an even layer. Top with the remaining 1 cup of Gruyère for that irresistible golden crust.
Step 8: Bake the Dish
Place the baking dish in the preheated oven and bake for 15-20 minutes, or until the cheese is melted, bubbly, and golden brown. Keep an eye on it to achieve that perfect crispy top without over-baking.
Step 9: Rest and Serve
After removing the dish from the oven, let it rest for 5 minutes to set slightly. Garnish with fresh thyme leaves for a pop of color and flavor. Serve your Baked French Onion Gnocchi warm, paired delightfully with crusty bread for a truly cozy meal.
